Step by step process
-
Step 1
Cover furniture and carpets, and keep windows and doors fully open to ensure good ventilation during the application and drying processes.
-
Step 2
First, simply brush out any loose particles and touch in nails and screw heads with oil based paint. Ensure all wiring is insulated.
-
Step 3
Now you're ready to fill, use Plaster Repair Polyfilla - ready mixed plaster on holes up to 2 inches deep. If your hole is deeper, create several layers, waiting for the filler to dry between each one.
-
Step 4
Stir the product to a smooth consistency then apply with a filling knife, trowel or float, with upward sweeping strokes. Maintain a firm, even pressure.
-
Step 5
Gently smooth off with a clean, wet float cleaning and wetting the float between strokes.
Alternatively use a length of straight wooden batten, drawing it gently across the surface, wetting as required.
-
Step 6
Once the surface is firm but before it dries hard, re-wet and polish with a clean float for a good finish.
-
Step 7
Allow to dry for at least 24 hours or several days for deeper repairs.
-
Step 8
To achieve a perfectly smooth finish, now apply Finishing Skim with a paint brush using upward strokes.
-
Step 9
Smooth over using the free spreader moving in an upward curve, maintaining firm, even pressure. Don't worry about small irregularities or 'tramlines'.
-
Step 10
Allow to dry for 2 to 3 hours until the surface appears matt. Now, use the spreader to achieve a flat smooth finish, rewetting the surface if necessary.
-
Step 11
Allow to dry for 24 hours.
If painting, prime before applying emulsion or if papering, seal absorbent surfaces first.
